Charting the evolution of the legend of the Grail, this revised edition of Giles Morgan's The Holy Grail offers insight into the shift from Celtic paganism to Christianity in Europe. Morgan traces the influence of Eastern mysticism emerging in the Grail romances as a result of the clash of cultures and the mixing of ideas during the crusades. In later centuries the Grail has come to symbolize the ultimate spiritual achievement, and has fascinated such thinkers as Carl Jung, T.S. Eliot, and William Blake. In a new chapter Morgan follows the renewed interest in the Grail—and its radical reinterpretation—since the advent of The Da Vinci Code.
